摘要： A plastic container, particularly suited for returnable and refillable PET carbonated beverage bottles, having an enhanced level of crystallinity in the sidewall but maintaining a very low level of crystallinity in the base. The container can withstand higher caustic wash temperatures and exhibits reduced flavor carryover from one product to another. The container is formed from a preform, wherein a sidewall-forming section of the preform is initially expanded and then heated to contract and crystallize the same before being reexpanded, and a base-forming portion of the preform is shielded from the heat treatment and expanded either before or after the heat treatment.

摘要： An injection molded plastic preform for forming by blow molding a container such as a bottle. The preform is of a laminated construction and in the body area includes inner and outer layers of the same plastic and an intermediate layer of a different plastic. The bottom portion of the preform is provided with a core layer of still a third plastic with the injection temperature of the third layer being sufficient to erode the contacted part of the intermediate layer which is of a lower melt temperature. The third plastic may be the same plastic as the first plastic, but injected at a higher temperature. Generally speaking, the neck finish of the preform will be of a single layer of the first material, the body of the preform will be of a three ply construction which is also true of the bottom with there being an intermediate area of five ply where the bottom core layer projects into the lower portion of the intermediate layer.

摘要： A plastic preform from which a plastic container is blow molded. The preform replaces a three layer preform by providing a preform which is of a five layer construction in the base forming portion thereof and wherein a secondary material which forms the core layer of the three layer preform construction is divided into an inner intermediate layer and an outer intermediate layer by a third injection of material. The third injected material is preferably the same material as the primary material which is first injected. This results in the reduction of the cost of the preform and also provides remaining in the injection nozzle a quantity of the last injected material which is the same as the first injected material for the following preform in the same preform injection mold cavity.

摘要： This relates to the base configuration of a biaxially oriented blow molded thermoplastic resin container. It has been found that by assigning more space to the ribs between adjacent legs and feet, during the blow molding of a preform, there is proportionally less thinning of the material of the preform in accordance with the greater width of rib, thereby providing greater strength in the high stress area of the base structure with a resultant lesser failure due to stress cracking.

摘要： This relates to a multilayer preform and a container blow molded from such preform wherein both the preform and the container are of a multilayer construction with there being utilized as an oxygen scavanger and oxygen barrier and a blend of either PET/MXD-6 nylon or PET/MXD-6 nylon/Co. In the resultant container, the percentage of MXD-6 nylon will be less than 1% and the container will be directly recyclable. Also, the percentage of MXD-6 nylon in the container will be such that there will be no noticable reduction in the clarity of the container. Also, because PET forms a part of the blend which provides the oxygen scavanger and barrier, the layers in the container will be bonded to one another.

摘要： A polyester preform which is injection molded preferably of PET and wherein the preform is provided with a molded neck finish or neck portion inlcuding threads which are molded to a high tolerance and wherein the neck finish may receive a closure cap of the type having a tamper indicating band which engages over a retaining bead also molded to a high tolerance as part of the neck finish. In order to maintain the container which is blow molded from the preform in axial alignment with the neck finish and thus eliminate the perpendicularity problem, a ring of the preform immediately below the flange which functions as the capping ring, is heated to a high temperature and crystallized. In a like manner, the end sealing surface is also heated to a high temperature and crystallized. The remainder of the neck finish remains in its amorphous state without disturbing the configuration of either the threads or the retaining bead. This combination of crystallized portions with the remainder of the neck finish remaining amorphous assures a high quality connection between a closure cap, whether the closure cap is formed of plastic or metal, while providing the end sealing surface with a hard tough finish resisting deformation and at the same time reducing the closure cap removal torque.

摘要： This relates to a preform which is injection molded and which is especially intended for use in the blow molding of a container suitable for receiving a hot fill product. Most particularly, the neck finish of the preform, which becomes the neck finish of the resultant blow molded container, is reinforced against axial compression or foreshortening as may occur when the neck finish is heated to a temperature approaching the glass transition temperature of the polyester from which the neck finish is formed. So as to resist deformation of the neck finish, the neck finish is provided on the interior surface (mouth) thereof with a plurality of axially extending, radially inwardly projecting, circumferentially spaced ribs. If the thread means of the neck finish for receiving a closure is of the interrupted type, there will be at least one rib for each thread element.
